These specifications help maintain the battery’s health, minimize sulfation, and ensure stable charging in various climates. This makes the battery suitable for solar systems, standby power, and environments with fluctuating temperatures.

 Wide Operating Temperature Range

This battery is designed for environments that experience both high and low temperatures.

• Charge: -15°C to 40°C
• Discharge: -15°C to 50°C
• Storage: -15°C to 40°C

Thanks to its rugged build and stable chemical structure, the WPL200-12N performs reliably all year long—even during harsh winters or hot summer seasons.

Long Shelf Life and Excellent Charge Retention

When stored at 20°C, the battery maintains a high percentage of its charge:

• 1 month: 98%
• 3 months: 94%
• 6 months: 85%

This strong charge retention ensures the battery remains dependable during long storage periods, making it suitable for emergency backup systems, seasonal equipment, and long-term installations.

 Extended Service Life for Professional Use

The WPL200-12N is built for endurance. With an expected design life of 10–12 years (Eurobat classification), customers can count on long-term performance with minimal maintenance. This lifespan makes it a cost-effective investment for businesses and power-intensive setups that demand stable, uninterrupted energy.

 User-Friendly Terminal Design

This model comes equipped with F18 terminals (M8 bolt type).

• Recommended torque: 12 N-m
• Maximum torque: 15 N-m

These strong, corrosion-resistant terminals ensure secure connections, improved conductivity, and easy installation in various power systems. They support heavy cables and high current loads without risk of loosening or overheating.

Accurate Size for Easy System Integration
